It is not common for a Koala to have twins, and regrettably in this instance the Mum was struck and killed by a passing car. Fortunately, the driver stopped, and took the mother to the local vet, not knowing she was dead, – where it was discovered she had these twins in her pouch.
Here’s a set up photos that show their maturation. In the first photo the tiny koala is being fed with syringe … sooo tiny!!
